3 Short-Range Comms & IoT Mode
3.4 HRP UWB Demodulation Measurement
–
The RBW to be used in the calculations is the equivalent –3 dB bandwidth of the
current RBW filter
–
The rules apply whether in swept spans, zero span, or FFT spans

IF Gain
Enables you to set IF Gain to Auto (see "IF Gain Auto " on page 526), Low Gain (OFF)
or High Gain (ON: extra 10 dB). These settings affect sensitivity and IF overloads.
To take full advantage of the RF dynamic range of the instrument, a switched IF
amplifier with approximately 10 dB of gain is available. When it can be turned on
without an overload, the dynamic range is always better with it on than off.
Only applies to the RF input. Does not apply to baseband I/Q input.
